IMPROVEMENT IN CALENDARS FOR CLG CKS AND WATCHES.

Specification forming part of Letters Patent No. l76,043,dated April 11, 1876 application-filed March 17, 1876.

To all whom it'mag concern:

of East Olarkson, in the county of Monroe and State of New York, have invented a new and Improved Combined Calendar and Time- Piece; and I do hereby declare that the following is a full,'clear,'and exact description of the same,-reference being had to the accompanying drawing, forming part of this' I that projectsthrough the dial l,'and carries specification, in which- Figure 1 is a view of the calendar devices with the dial removed, the said devices being located between the dial and the operating parts of the watch; Fig. 2, a front view of the Figs-3 and 4 are details of the stop and connecting mechanism through which dial.

the calendar devices are operated.

My invention relates to the improved construotion and arrangement of a calendar in a time-piece, so combined therewith as to indi-' cate the day of the week and month, and the month-of the year.

My improvement consists in making the calendar devices independentof'the effect of quently render its construction cheaper, and

its operation more reliable.

In the drawing, Fig. 1 shows the calendar mechanism, which is located just between the dial I and the rear portion of the watch containing the time-movement, the said calendar mechanism being attached either to a separate cap, G, as shown, or to the upper surface of the movement.

Eis a toothed wheel, which lcall the monthwheel, because it is provided with twelve teeth corresponding to the twelve months of the year, which wheel is arranged to move one tooth for each month, and revolve once ayea-r. This wheel is pivoted to the cap G, and is provided with a stem, which projects up through the dial I, and carries an index-hand,

' E, which, as the wheel rev0lves,'points s'uc- Be it known that I, MINER H. PADDOG'K,

cessively to the twelve initial-letters forming the month dial. D is a second toothed wheel, which I callthe week-wheel, because it is provided with seven teeth corresponding to the seven days of the week, which wheel is arranged to move one tooth each day, and revolve oncea week. This wheel is also pivoted to the cap G, and is provided with a stem an index-hand, D, which, as the wheel revolves, points successively tothe'difierentletters indicatin'g'the days ot' the week, and forming the week-dial.

F is an annular calendar orday-wheel, arranged upon the ou'tered'geof cap G, concen tric therewith, andhaving upon its inner perimeter notches or teeth, which are thirtyone in number to correspond to the greatest number of days in "a month. This'annular calendar bears upon its face numbers ranging from 1 12031., which pass successively beneath the opening El in the dial,'and'are visible one ata time through the same, for the purpose of indicating the days of the month. Projecting inwardly from the annular calendar F is a'tooth, d, which, as it'passes in its revolution oncea -month,'strikes the teeth of'the month-wheel E and rotates it'onetooth to set its indexhandior the next month. The said annular calendargears continuously with the week-wheel D, and moves with it one tooth or notch each day, thesa'id motion being imparted through wheel D by the following mechanism: 'A is "a disk, bearing u on its periphery a single tooth, c. This disk is located upon the winding-shaft, which receives the key, and moves therewith. B is a disk forming a stop mechanism, which is constructed, as usual, with alternate notches, f, and curved faces, the said notches, as shown, being five in numberfor five complete revolutions of the winding-stem and disk A. The

disk B I construct with a transverse groove,

in which slides a bar, 0, having projections at b and c to prevent it from slipping out, and a tooth, to, which, when this end of the bar is projected, strikes against the teeth of wheel D and rotates it one tooth. The tooth or is placed to one side of the central line of the bar 0, so that its end at b may form the bottom of the fifth notch, for the purpose about to be described. The device, as shown,represents the watch or clock run down, or nearly so, and about to be removed, the arrows indicating the direction of the wheels for the said winding. The tooth a having been projected by the unwinding of the watch, and the consequent striking of end 0 of the slide by the tooth e, the next revolution of the stem brings the tooth 0 into the next notch, and tooth a is made to turn the wheel D and its connected annular day-wheel F the distance of one notch or tooth. The successive revolutions of the stem in winding them brings tooth c. in the other remaining notch f, until it strikes the last notch, formed partly by a b of the slide 0. This slide is then driven back by tooth 0,

so that while the spring is running down duringfthe day the tooth of the slidedoes not engage reversely with the wheel D, and the slide is in position to be projected by the striking of the end c. of the slide by the tooth e as the latter enters the notch in which 0 is located.

I. would have it understood that although I i have shown the slide 0 as the preferable mode of imparting the motion to the wheel D, I do not confinemyself to the same, as a pin may be placed upon stop B, and arranged to operate uponfa lever, to produce the same general effect;

From the above description it will be seen that the winding of the time-piece operates simultaneously but independently upon both the calendar and the mainspring, to set the one and Wind the other, which winding may be effected either through an ordinary key or by a set of stem-winding devices.

The winding of the watch also records itself upon the dial-face, so that whenever the question as to the winding is in doubt it is not necessary to apply the key to ascertain the fact In order 'to compensate for the irregularity arising out of the different number of days in the different months, the hand D upon the week-wheel is made adjustable in its connection with wheel D, and the wheel so arranged that the annular day-wheel may be set thereby. For this purpose the stem 9 of the wheel D is made square, or otherwise constructed so as to permit the wheel and its connected I claim as new is 1. The combination, with atime-piece, of a calendar, adapted to be operated through the winding-stem, independently of the efl'ect of .the mainspring, for the purpose described.

' 2. The combination, with the watch-dial having perforation H, of an annular numbered calendar, F, substantially as described.

3. The combination, with the calendar devices and the winding-stem, of a self-adjusting device, which alternately makes and breaks the connection between the said calendar devices and stem, according to the direction .in which the stem is turned, substantially as described.

4.. The combination of the annular calendar F, having tooth d, with the month-wheel E, carrying an index-hand, substantially as, described. 4

5 The disk A, located on the winding-stem, and having tooth e, in combination with the stop B, having slide 0 or its equivalent, as and for the purpose described.

6. The combination of annular internallynot'ched calendar F, having tooth d, the month-wheel E carrying an index-hand, the week-wheel D carrying an index-hand, the stop B having slide G, and the disk A attached to the winding-stem, and having tooth e, substantially as and for the purpose described.

7. The annular calendar F, having internal teeth or notches, in combination with the wheel D, meshing therewith, and having a stem, made square or otherwise shaped, :to permit the easy setting of the annular daycalcndar by hand, as described. MINER HAMLIN PADDOOK. Attest:
